Description

Technical Field

[0001] The present invention relates to the technical field of mechanical support equipment, and in particular to an adjustable mechanical support tool. Background Art

[0002] A hydropower station consists of a hydraulic system, a mechanical system, and an electric energy generating device. It is a water conservancy hub project that realizes the conversion of water energy into electric energy. The sustainability of electric energy production requires the uninterrupted use of water energy in the hydropower station. Through the construction of the hydropower station reservoir system, the distribution of water resources in time and space is artificially adjusted and changed to achieve sustainable use of water resources. In order to effectively convert the water energy in the reservoir into electric energy, the hydropower station needs to be realized through a hydro-mechanical system, which is mainly composed of a penstock, a turbine, a generator, and a tailwater pipe.

[0003] The hydroelectric system realizes the conversion of water energy into mechanical energy through the cooperation of the pressure water pipe and the turbine, and finally realizes the purpose of using water energy to produce electricity by using the linkage relationship between the turbine and the generator. The amount of water energy converted into electricity in the reservoir is closely related to the magnitude of the force at the mouth of the pressure water pipe. Therefore, factors that affect the force at the mouth of the water pipe, such as the reservoir water volume, reservoir water level, and the inclination angle of the pressure water pipe, directly affect the efficient conversion of water energy into electricity. Therefore, the process of electricity production in a hydropower station is how to coordinate the operation between the reservoir and the hydroelectric system and between the various parts of the hydroelectric system. The hydropower station system is essentially a hydroelectric coupling system.

[0004] In the hydropower station system, the base of the power equipment is generally a square frame base surrounded by a thin plate frame. These bases need to be regularly inspected and maintained. During the inspection and maintenance of these equipment, it is sometimes necessary to dismantle and weld the side panels or cover plates. When welding the thin plate frame, due to the thinness of the plate, the thermal stress and thermal strain during the welding process can easily cause the plate to deform; this deformation will affect the dimensional accuracy, appearance quality and performance of the welded parts, and may even cause the welded parts to fail and be scrapped. Welding deformation can be divided into overall deformation and local deformation, such as longitudinal and transverse shrinkage, bending deformation and twisting deformation. Factors that affect the deformation of thin plate welding include welding process parameters, welding methods and methods, the number and cross-sectional size of welds, the shape and size of welded structural parts, the thermal physical properties of welding materials, and the supporting structure for welding.

[0005] In traditional welding methods, manual operation is usually required when welding rectangular or square thin plate frames. However, since the plates are particularly thin, they are prone to deformation, which affects the welding quality. This is not only inefficient, but also difficult to ensure accuracy. In addition, manual operation may lead to safety accidents due to improper operation, and plate deformation may lead to material scrapping or plate straightening during welding. In order to improve production efficiency and processing accuracy, it is necessary to develop an adjustable mechanical support tool to achieve fast and accurate clamping and positioning of the plates, and at the same time, it can limit and clamp the four sides of the plates and fix and limit the upper cover.
